WILLIAM BROWN, OF WEST BRIDGEWATER, PENNSYLVANIA.

NUT-LOCK.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed July 10, 1907. Serial No. 383,020.

To all whom. lit may concern:

Be it known that I, WILLIAM BROWN, a citizen of the United States of America., residing at ll'est Bridgewater, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Im )rove'ments in Nut-Locks, of which the foliowing is a specification, reference being had therein to t 1e accompanying drawing.

,This invention relates to improvements in nut locks, and the invention has for its object thep ovision of )ositive and reliable means for pr yenting time 'accidental rotation of a nut upon a bolt, after it has been once placed thereon. il,

Anotherobjeet of this invention is to provide anut lock )articularly designed for the nuts and bolts oirail joints, and such elements subjected t 'avibratory stresses and strains.

To this ei "UL have devised a simple and inexpensive n .rtlock, wherein a slotted bolt, slotted washer andapiece of wire are used for locking the lint in engagement with a bolt, the wire being easily and quickly bent to release the nut when itis desired to remove the same from the bolt.

In the drawings, Figure 1 is an elevation of my improved nut lock, Fig. 2 is a longitudinal sectional view of the same, and Fig. 3 is a perspective vview' of a )ieceof wire constructed in accordance with my invention, for loc-king a nut upon a bolt.

In the accompanying drawings, Rand '2 designate two pieces of material through which a. bolt 3 passes, the threaded end t of said bolt being provided with a longitudinally disposed slot 5". ln connection with the -bolt 3 I use a conventional form of nut 5, and a washer 6, the washer' being provided with a radially disposed slot 7, the object of which will presently ap pear.

' My improved nut llock constitutes a piece of vfire S having one end bent substantially at rightangles thereto, as at 9, and then bent to provide a triangular configuration, as at 10.

After the washer 6 has been placed upon the threaded and slotted end of the bolt 3, the piece of wire Sis placed in the slot 5" of the bolt. C3, and then the nut 5 is rotated until the same engages the washer 6. The triangular coniigurared end of the piece of wire 8 is then bent over t'new'asher to engage one side of the nut 5, as at 11, while the opposite end of the piece of wire 8 is bent downwardly as at 1'2, to engage the outer face of the nut 5. It

will thus be observed that the triangular configura-tion of the piece of wire 8 prevents the nut 5 from rotating, as long asa portion of the piece of wire is retained within the longitudinally dis )osed slot- 5a1 of the bolt 3, 60 therefore it willi be observed that the triangular portion may be dispensed with.

The ends of the piece of wire constituting lmy improved nut lock can be easily and quickly bent to release the nut 5 at any time 65 itis desired toremove the nut from the bolt 3.

Having fully described my invention, what I claim and desire to secure by Letters Patent is lIn a nut lock, the combination with a bolt having a screw threaded end provided with a longitudinally disposed groove, a hexagonal nut, adapted to be mounted upon the srewthreaded end of said bolt and having af portion of its outer face iiattened, a washer positioned against the nut and having its inner face formed with a radially extending groove constituting a scat, the depth of said groove approximately half the thickness .of the washer, said groove of a length as to extend from the inner to the outer edge ofthe washer and a fastening member consisting of an elongated cylindrical bar bent to have its outer end overlap a part of the flat portion of the outer face of the nut, said member furtherA having a portion of its length positioned within the groove of the bolt and extending lf through the nut and washer, said member further having a portion'of its length engaging in said seat, t ie diameter of the member E,

with respect to the depth of the groove which constitutes the seat being such that that pox-- tion of said member which is mounted in said seat does not project beyond the inner face of the washer, said member having another portion of its length arranged exteriorlymf the washer and nut and bent to engage th periphery of the washer and then at an in clination, that portion of said member which engages the periphery of the washer and the side of the nut being substantially triangular in contour with the apex of the triangle p0- sitioned against the periphery of the washer and with the base of the triangle bearing directlv against the nut, the ends of. said member being disconnected from each btller- In testimony whereof I ailix my signature in the presence of two 'itnesses YILLIABI BRO'WN Witnesses: EDWIN S.
